Need HELP swapping a Vision pro 8320u1008 to an IAQ one

I'm not that familiar with Nordyne VS units, but I don't see a DeHum anywhere to slow blower down 20% for dehumidification. Does the Pro 8000 stat you have now have dehum? That could be set and it would run a/c up to 3 deg lower than setting to try and reach desired humidity level.

If you look at the pic of the dip switches. Their are 2 HUM terminals that are jumped. The Vision Pro 8320 does not have dehumidificaiton control. That is the reason I want to swap it out to the new IAQ VIsion Pro.

Sorry I'm used to hum meaning humidify. According to Nordyne it can be used to dehumidify.

8. OPTIONAL HUMIDISTAT(Variable Speed Only)The optional humidistat may be installed in thereturn air duct to provide excellent humiditycontrol when needed and maximum systemcapacity and energy effi ciency when humiditylevels are normal. The humidistat senses whenhumidity in the return air stream is above a presetlevel (fi eld adjustable) and sends a signal to themotor to reduce the airfl ow so that more moisturemay be removed until the humidity level drops.The air handler is pre-programmed for humidistatoperation. Remove jumper connector installedbetween the two terminals marked “HUM” onthe circuit board.Note: The 15+ SEER air handlers that arematched with a 2-stage cooling outdoor unitand the humidistat is installed will not dropbelow 75% of the selected blower speed whenthe system is operating in lo-cool mode and thehumidistat opens.Installation— Install the humidistat in the returnair duct as directed in the installation instructionsincluded with the kit. Wire the humidistat throughthe low-voltage wire entrance in the air handler(Figure 1) to the quick-connect terminals marked“HUM”. Wire the humidistat to open on rise inhumidity.

So can it be wired into the VIsion Pro IAQ then? Please tell me it can as I have the thermostat here. My intention was to use it to control the humidity in my house. FLorida is Hot and Humid..lol

I see you are in Fl as well. What is your humidity level in the house? It should be on a properly set up system around 50% these days. If not your system may have not been set up correctly, IE too much airflow, A/C too big ect.
